The problem of bark waste that is generated by the forest products industry in the United States has become increasingly important. The major overall goal of the work covered in this report was to use physical and chemical sciences in coordinated studies to promote economic uses of bark in order to relieve pollution created by present methods of disposal. Physical utilization research included: investigating the preparation of bark pellets from bark; determining the components responsible for 'self-bonding' of bark; and investigating potential products from or applications of bark wastes obtained from production sources. Chemical utilization research included: preparing, for chemical studies, natural bark, bark that had been ammoniated to contain 4 percent nitrogen, and bark that had been molded into pellets and then broken down into small particles; and investigating the chemical composition of each type of bark prepared.
